IMPROVEMENT IN` BINDING AI'TACHMENTS TO HARVESTERS.

iSlpeeicat/on forming part Qf Letters Patent No. 37,852, dated Jlzwch 10, 1863.

To all 'whom it may concern Be it known that we, H. M. BURsoN and W. W. BURSON, of Atkinson, in the county of Henry and State of Illinois, have invented a new and useful Improvement in Grain-Binders; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawing, forming part of this specification, in the several figures of which similar characters of reference denote the same part.

Figure 1 is a side elevation, the full lines showing the arm in position when around the gavel, the dotted lines its position ready to receive the gavel. Fig. 2 is a plan view.

Our invention has reference to the binding of grain upon the reaper-platform with twine or Wire; and consists of certain combinations of devices, hereinafter to be mentioned.

In the drawing, B is the base or platform, in which are fastened the uprights A A, supporting the arm C, which turns upon its bearingcta. -Thc main arm C, Fig. 1, and fore arm C are jointed at Z. The handle-piece D joins C', extending beyond the joint b at e. The lever E is secured to the arm C at d, and to the handle-piece D at f. The rear end, relieved by friction-rollers, moves inthe groove g.

The Wire-reel G rotates upon its bearing It, and is secured upon the rear extension of the arm U, whereby its weight, as also the weight of the band material wound upon it, may serve to counterbalance the weight of the arm and its attachments.

The ratcheted pulley N of reel G acts upon ratchet-spring L when the arm is being raised, as shown in dotted lines, Fig. 1, allowing the band material to unwind until arriving at spring-ratchet M, when the reel is held from turning or turned back, holding the wire stretched when the arm is fullyraised.

The tightening-cord H attaches fore arm C at i, passing through loop m of cord I, under friction-roller j of slide F, over the pulley k, secured to the rear extension of arm C, and has attached. to it the weight K, Fig. 1.

The cord I is secured to handle D at f, as also slide F, by which means they are raised much more rapidly as the lever E changes from a horizontal to a perpendicular position than if secured 'to the main arm G, which relieves the sheaf when bound from the hinderance of the tightening-cord in its removal from the binding-platform.

In operating, we take hold of the handle O and raise it. The rear end of lever E, guided by groove g, directs the handle-piece D, acting upon fore arm G', in such manner that the point of C moves nearly horizontally until it reaches the point designed as the limit of its grasp, when itis raised nearly perpendicularly, and is finally drawn in toward the uprights. By this movement the least possible amount of wire is being drawn out, while the band, being held nearly perpendicular, is less in the way of bringing the gavel to the binder than those which hold the wire more nearly horizontal.

While the arm is being raised thcrear extension is lowered, carrying the reel G downward, whereby the ratcheted .pulley N is brought in contact with spring ratchet L, causing the reel to give oi' the band material (wire or twine) until the spring-ratchet M is reached, when the reel is held from giving off more, and the band material is held tight, when, the gavel being shoved 'to the binder, the springratchet L acts continually to draw the band tightly around the gavel. This ratcheted arrangement ot pulley N and springs L and M is designed to offer little or no resistance to the reel turning in one direction, while any desired resistance can be given itin the other, still allowing a sucient length of band to be drawn oft'.

The tightening-cord H is thrown around the gavel every time the band is, and by placing the pulley lc back of the point of rotation ot' arm (l, that pulley is lowered while the fore arm is raised, thereby compensating for the length of cord drawn out, and avoiding the lifting of the weight R, attached to that cord, as in the patent of W. W. Burson, dated February 26, A. D. 1861. The cord I,when the "arm is being raised, lifts the cord H from the sheaf, thereby aiding much in the ease of its removal.

Vhat we claim as our invention, and desire to secure by Letters Patent, isy 1. The combination of the arm C, fore arm C', handle-piece D, lever E, with groove g, acting substantially as and for the purpose set forth.

2. The combination of the ratchet-pulley N with-spring-ratchets L and'M, acting substan-V vIn testimony whereof we havehereunto set tiallly as described. ourhzmds and seals.
